Test conditions and notes11
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
- 2. Please refer to "DRIVING METHODS OF LED MODULE". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
- 3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
- 4. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
- 5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 6. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
- 7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
- 8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
- 9. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
- 10. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.

FAQ
Can I use the ELG-100-C350B to drive LED modules in outdoor signage applications?
Yes. The ELG-100-C350B carries an IP67 waterproof rating, so it can withstand rain and dust ingress in exposed outdoor signage installations. It delivers a constant 350mA across a CC voltage range of 143–286V, making it suitable for series strings of high-voltage LED modules used in channel letters and illuminated signs.
Is the ELG-100-C350B suitable for powering LED downlights in a recessed ceiling fixture?
Yes. The driver operates over a wide input range of 100–305VAC and maintains a constant 350mA output, which is appropriate for mid-power LED downlight engines designed for that current. Its metal case and IP67 rating also support installation inside tight fixture enclosures where heat and moisture can accumulate.
Can I use this driver for an LED array installed in a cold-storage or refrigerated environment?
Yes. The ELG-100-C350B is rated for a case temperature (Tcase) down to -40°C, making it compatible with cold-storage rooms, freezer corridors, and similar low-temperature environments. Note that its working humidity rating is 20–95% RH non-condensing.
How many LEDs can the ELG-100-C350B drive in series?
The driver supports a CC voltage range of 143–286V. The number of LEDs that can be connected in series depends on the forward voltage of each individual LED — divide the usable voltage range by the forward voltage of your LED to determine the compatible string length. The driver will regulate at a constant 350mA regardless of the exact string voltage within that range.
Does the ELG-100-C350B support dimming?
Yes. The B-suffix variant indicates built-in dimming capability. It supports three-in-one dimming (0–10VDC, 10V PWM signal, and resistance), allowing integration with standard lighting control systems without additional dimming hardware.
What is the difference between constant current ELG-100-C350B and the constant voltage variants in the ELG-100 series?
The ELG-100-C350B is a constant current driver that outputs a fixed 350mA and allows the voltage to vary between 143–286V depending on the LED load. A constant voltage driver instead holds a fixed output voltage and lets the current vary; constant voltage models are not covered by the ELG-100-C datasheet. Constant current drivers are preferred for direct LED string driving where precise current control is needed to prevent overcurrent.
